WINDOW OPERATING AND LOCKIN'G DEVICE. 5 V

A plication filed May 1 922, Se i l No. 562,045. Renewed January 19,1925.

To all whom it may concern,"

Be it known that I, JOHN M. PRICE, a citi- Zen of the United States ofAmerica, and resident of Des Moines, Polk County, Iowa, have invented anew and useful indow Operating and Looking Device, of which thefollowing is a specification, V

An object of this inventionis to provide improved means for raising andlowering individual window sash and locking the same in any desiredposition.

A further object of this invention is to provide an improvedconstruction for window operating and locking .mechanism, adapted to beoperated by a removable crank, the operating devices being concealed inpart and in part located flush with a window frame, thus avoidingprojectingelements objectionable in appearanceor likely to becomeentangled with window draperies.

A further object of this invention is to prov de improved means forournallng operating devlces,

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which- Figure 1 is anelevation partly in section illustrating a window frame containing twooverlapping sash and means for operating said sash independently of eachother. Figure 2 is an elevation of a portion of a face casing showingone of the operating devices and one of the locking devices mountedthereon, on a larger scale than Figure 1. Figure 3 is a cross-section onthe indicated line 33 of Figure 1, on an enlarged scale, the lockingdevice being omitted and the crank being shown detached' Figure 4 is" across-section on the indicated line 44 of Figure 1, on an enlargedscale, the locking devices being shown in looking position.

For purposes of illustration there is shown a window frame ofconventional form, an upper sash 10 and lower sash 11 being slidinglymounted therein in parallel planes in a common manner. Referencehereinafter will be made to various particular elements of the frameconstruction.

Each sash 10, 11 is formed with recesses in the outer margin of the leftstile thereof and anti-friction rollers 12 are journaled in saidrecesses and are adapted to engage and travel on the adjacent ja-mbofthe window frame and lessen frictional engagement between said sashand jamb. Grooves are formed-in the outer margins of the right stiles ofthe sash 10, 11 and racks13, 14 are mounted rigidly in said grooves andhave their teeth towardthe adjacent jamb 15 of the window frame.Recesses are formed in theright inner face casing 16 of the windownframe, one above the other, preferably on opposite sides of thehorizontal plane of the meeting rails of the sash 10, 11, and holes 17,18 are formed in the face casing centrallyof said recesses, the holesbeing of materially less diameter than the recesses. Sleeve bearings 19,20 are mounted respectively in the holes 17, 18 and are of differentlengths, the longer bearing 19 extending across the plane of the sash 11and substantially to the median line of the sash 10, whereas the shorterbearing 20 extends substantially to the median line of thesash 11. Thesleeve bear ings 19, 20 are formed respectively with head flanges 21, 22which are preferably circular in form and are received and seated in thebottom of the recessesand' secured to the face casing 16 by screws 23.Operating shafts 24, 25 are journaled in and project at both ends fromthe sleeve bearings 19, 20 respectively and said shafts are formed withheads 26, 27 on their outer ends, which heads are of less diameter thanand overlie the head flanges 21, 22. The outer surfaces of the heads 26,27 preferably are flush with the outer surface of the casing 16. Spurgears 28, 29, preferably of like diameter, are mounted on the inner endsof the shafts 24,

25 respectively and are removably secured thereto by hub set screws 30,31, said gears respectively abutting the inner ends of the sleevebearings 19, 20. Thus provision. is made for limiting or preventinglongitudinal movement of the shafts 24, 25 in the sleeve bearings. Slots32, 33 are formed in the j amb 15 at different altitudes and in parallelvertical planes and the spur gears 28, 29 project through said slotsinto meshing engagement with the racks 13, 14. The

heads 26, 27 of the shafts are formed with angular sockets 34, 35 inalinement with the axes of the shafts and said sockets are adapted toreceive selectively an angular head on a hand wrench 37 whereby theshafts and heads thereon may be rotated in either direction manually.Included in the manual ro a i n f the shafts y means of the wrench 37there is the function of controlling the descent of a sash by gravity.Each head 26, 27 is formed with ratchet teeth 38 adapted to be engagedby a gravity pawl 39 mounted on either of the head flanges 21 or 22, thedirection of engagement of the pawl with any teeth being such as toprevent accidental descent of a sash 10 or 11. Each head flange 21, 22is formed with a series of holes etO arranged in a circular rowconcentrio with the axis thereof and each head 26, 27 is formed with asingle hole 41 adapted to register at times with one or another of theholes 40. Pins 42, t3 are suspended by hangers 4d, &5 from the facecasing 16 and said pins are adapted to be mounted in registering holes40, el 01 the respective operating devices and, when so mounted, serveto prevent movement of a sash, gear and head in either direction,whereby provision is made for locking each operating device againstmanipulation or accidental rotation and holding the sash in any positionin which it may be placed manually.

The head flanges 21, 22, screws 23, heads 26, 27 and pawls 37 may befinished in any desired manner to harmonize with the finish given to theface casing 16. The arrange ment of the heads of the operating devicesand their supports in the recesses in the tace casing 16 avoidsobjectionable appearance and danger ofentangling 0t draperies with saidelements. The crank 37, pins 42, 4:3 and hangers 44, 45may beselectively or entirely removed when not desired for use and storedextraneous t0 the window.

recess and ahole at the center thereof and jamb formed with a slot, of asleeve bearing mounted through said hole and formed with a head flangeseated in said recess, a shaft journaled in said sleeve bearing andformed with a i'atcheted head overlying said head flange and containedwithin said recess, a gear removably mounted on said shaft, abut-- tingsaid sleeve bearing and extending through said slot, a pawl pivoted onthe head flange of said sleeve bearing and adapted to engage theratcheted head of said shaft, and means for rotating said shaft.

2. In a device of the class described, the combination with a casingformed with a recess and hole at the center thereof and a jamb formedwith a slot, of a sleeve bearing mounted through said hole and formedwith a head flange seated in said recess, a shaft journaled in saidsleeve bearing and formed with a head overlying said head flange andcontained within said recess, a gear mounted on said shaft, abuttingsaid sleeve bearing and extending through said slot, said head flangebeing formed with a series ot-holes, the head being formed with a holeadapted to register therewith, a pin adapted to be mounted inregistering holes, and means for rotating said shaft.
